Abstract

With the use of carbon isotopes of the soil organic matter (SOM) and of modern plants, it is intended to study the dynamic of expansion and regression existing between ecotones of forest-cerrado and forest-caatinga, located in Pernambuco, and of forest-cerrado in Maranhão. Based on datings for 14C of the SOM, the study should outline the probable changes of vegetation and climate that occurred in these Brazilian regions, comprising approximately the last 15 thousand years.
